Charging of a lead acid battery can be done in various ways: Constant voltage charging is most commonly used for a sealed lead acid battery. The initial charging current in a constant voltage battery charger is limited by a resistor. Figure 1 below shows the charging over time for a constant voltage charger. Figure 1 Credit BB Battery
In this method the charging current is high in the beginning when a battery is in discharged condition, and it gradually drops off as the battery picks up charge resulting in increased back emf. Charging at constant voltage may be carried out only when the batteries have the same voltage, for example, 6 or 12 or 24 V.
The charging current is high in the beginning when the battery is in the discharge condition. The current is gradually dropping off as the battery picks up charge resulting in increase back emf. The advantages of charging at constant voltage are that it allows cells with different capacities and at the different degree of discharge to be charges.
Constant current battery charging can be used is charging multiple batteries connected in series simultaneously. An example of the charging circuit and curve can be seen below in figure 2. Figure 2 Credit BB Battery
In the multi stage charging of a lead acid battery, the charger goes into a bulk charging state where the current and voltage are at a higher rate to get a majority of the battery charged. The next stage of the charging process is also known as absorption charge.
In the constant voltage charging method, charging voltage is kept constant throughout the charging process. The charging current is high in the beginning when a battery is in a discharged condition, and it gradually drops off as the battery picks up charge. While charging a lead-acid battery, the following points may be kept in mind:
